2. Composite construction - Wikipedia

   en.wikipedia.org/wiki/Composite_construction

   A composite steel deck combines the tensile strength of steel with the compressive strength of concrete to improve design efficiency and reduce the material necessary to cover a given area. Additionally, composite steel decks supported by composite steel joists can span greater distances between supporting elements and have reduced live load ...

3. Orthotropic deck - Wikipedia

   en.wikipedia.org/wiki/Orthotropic_deck

   The same structural effects are also true of the concrete slab in a composite girder bridge, but the steel orthotropic deck is considerably lighter, and therefore allows longer span bridges to be more efficiently designed. Resistance to use of an orthotropic deck relates mainly to its cost of fabrication, due to the amount of welding involved.

4. Deck (building) - Wikipedia

   en.wikipedia.org/wiki/Deck_(building)

   A deck is also the surface used to construct a boardwalk over sand on barrier islands. Laying deck or throwing deck refers to the act of placing and bolting down cold-formed steel beneath roofing and concrete floors. This is usually done by an ironworker, sometimes in conjunction with a cement mason or carpenter. It regarded as one of the most ...

5. Deck (bridge) - Wikipedia

   en.wikipedia.org/wiki/Deck_(bridge)

   A grid deck uses beams and diaphragms as the supporting structure. The supporting system of a grid deck is analyzed using a grillage analysis. A slab deck is one where the deck is analyzed as a plate. If the slab has a stiffness that is different in two directions (at right angles), then the deck is known and analyzed as an orthotropic deck.

6. One Worldwide Plaza - Wikipedia

   en.wikipedia.org/wiki/One_Worldwide_Plaza

   Each floor slab is made of concrete, which is poured onto a metal deck. [41] The floor slabs measure 165 by 165 feet (50 by 50 m). [42] The maximum structural load on each column was 2,000 short tons (1,800 long tons; 1,800 t) on average. [41] These loads were carried down into the concrete spread footings at the building's foundation.
